    Do you know how to upgrade ver 3.5.1, that was installed with yum, to newest version?

    • Ravi Saive says:

      @Agust,

      Do a yum update, hope it will upgrade your Nagios version to most recent available version from repositories. Else, do a source installation for the latest version of Nagios.

    Hello Sir,

    I followed all steps you gave, but I’m unable to login web-interface, see below error.

    # curl -k http://172.25.9.11/nagios/
    
    Sample Output

    On my CentOS 7.2 I still had an issue even after setting the said SELinux security context.

    Following SELinux security context worked for me !!

    # chcon -R -t httpd_sys_script_exec_t /usr/local/nagios/sbin
    
  9. Larry says:

    After try to resolve the issue the below is what I got. I believe it is a permission it issue but I don’t know where to put the permission

    Forbidden

    You don’t have permission to access /nagios/ on this server.

    • Ravi Saive says:

      @Larry,

      It’s something SELinux preventing from the accessing the nagios page, try to set SELinux to permissive mode, you can use the following command to set:

      # chcon -R -t httpd_sys_content_t /usr/local/nagios/sbin/
      # chcon -R -t httpd_sys_content_t /usr/local/nagios/share/
      

      Don’t forget to restart the Apache service..
